MSI MS-6769 service archive, 1.79 MB, compressed as zip. Only the board code is given in the name, without revision, version or document type. After extraction, check whether it contains PDF drawings or binary firmware. Because MSI reuses an MS code across closely related boards with different revisions, confirm the revision printed on the PCB as well. Schematic data aids in tracing missing voltages and shorts, while a BIOS image should match the chip capacity and be written only after saving a backup.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @IT_SERVICE_WORLD. Enginerys does not host this file.
